I was walking the dog a few months ago and spotted a car where the windows were... weirdly foggy. Yellow-brown fog, and I realized after a minute that the car was on fire. So I banged on the house door several times, no response, eventually found a neighbor to call 911. When the fire truck showed up, THEN the owner of the car came to the door--he'd been sleeping upstairs and somehow hadn't heard the fuss.

Interesting and unsettling both.
